The F11 and D/L error codes are common to main board problems. We have had our washer since 2005. It started having D/L problems in 2006. Looking online at that time we learned to jiggle the wire harness. That worked sporadically, until we solved the problem by leaving the washing machine metal top cover off entirely, taking the plastic cover off the main board box, and taping the main board tray to the top rear of the washer. Putting the plastic cover back on the main board box always seemed to cause a problem.

Unwilling to face the ugliness anymore, we wanted to put the cover back on the washing machine two days ago. With everything back in place, we hit a wall of F11 errors. We were way past warranty phase, and badly in need of doing laundry on the weekend. No appliance repair shop or person was available for a fix.

The Motor Control Unit Power connector at the main board was loose, so I decided to see if re-soldering would do the trick. I removed the main board and looked at all solder connections under high power magnifying glass for glaring problems. All four pins of the Motor Control connector had visibly separated from their solder, and there was one pair of pins belonging to the big red resistor in line with the Motor Control connector that had a similar look. In fact there were slight vestiges of solder blowout originating from one of those pins calling attention to it. I re-soldered all those pins and put the board back in place. It worked for awhile, but we started getting D/L errors and F11 errors again. Oddly, they appeared when putting the main board box cover back on.

The main box cover has plastic pegs designed to push down on the main board when snapped on place. I cut the pegs shorter, but that did not help. Looking closer, the pegs are offset inward on the board, and one peg pushes into the black resistor in line with the Line Filter Connector. I figured with all the machine vibration, the black resistor would be affected by the tight tolerance.

I removed the main board again and looked even more closely at the solder around all pins. Sure enough, the solder at one of the black resistor pins showed signs of cracking. The pin could be seen moving up and down slightly with rocking of the resistor above. The Door Lock connector also pins showed signs of fatigue. Soldering all these distressed connections firmly back in place seems to do the trick .... for now. We need to order a replacement board, and keep it handy in case of final board failure.

Getting rid of mildew - Consumer Reports suggests leaving the door slightly ajar on all front loading washers. That has worked for us.

We have had the same problem for a long time now and our machine is 3 years old. We actually have clothes stuck in the machine getting moldy as we speak and I can't figure out how to get the door unlocked. I would like to try your suggestion, but I don't have the equipment you do and not sure if I'd make it worse. I hate to pay hundreds for a repair main, I'd almost rather just get a cheap washer and get rid of this. Can you just buy a new motherboard? How would you find out where to buy it and the model? Does it go by the machine model number? And do you think it'd have the same problems? I'd be willing to try anything at this point because we've been having to take our laundry other places now and it's getting ridiculous since we spend all that money to buy these machines.

Thanks for the help!

the error codes are F/11 SERIAL COMMUNICATION ERROR....Communication between the Central Control Unit (CCU)and the Motor Control Unit (MCU)cannot be sent correctly Potential Causes are#1check wire harness connection to the MCU,the motor,and Central Control Unit(CCU)#2Check the drive system for any worn or failed components #3ReplaceMCU #4ReplaceCCU#5Replace motor#6Replace wire harness ERROR CODE F/dl Door Lock Errow...a door lock error occures if the door cannot be locked.It will try to lock it 6 times before displaying the error. Potential Causes are#1door lock mechanism broken or removed from the door.#2Check door lock/switch assembly#3Check the wire harness connections to the door lock/switch assembly and Central Control Unit(CCU)#4Door lock/switch assembly failure.

I have the same problem, is there a way to fix it?

[roycbarney]

Where will you order the part from and how much is it?

roycbarney,

What is the complete model number of the unit and which part are you looking for?

Gene.

Ghw9400pw0, and thank you so much for responding to my post. I think we should all get together and petition Whirlpool for the replacement parts to fix this problem that it seems all the machines have.
